Answer:
x=6 because if you multiple 4x6 you get 24
not exactly sure but try
Do you want a proof or just the answer?
The answer is: the square (2.5x2.5).
-13 to 0 = 13 degrees changed. 0 to 22 is 22 degrees changed. 13 + 22 = 35 degree change.
10-3 = 7.
So there was a change of 35 degrees across 7 hours
35/7 = 5 degrees per hour.
